The traditional view of motor systems as a linear chain of elements switched on and off by command neurons has become increasingly difficult to maintain in the face of accumulating evidence against the existence of command elements. So far, however, the general formulation of an alternative approach has been lacking. This book, by summarising the evidence against the linear approach to motor systems, argues forcefully against it. Analyses are presented of motor systems ranging from the lobster stomatogastric system through molluscan systems, leech movement, insect singing and locomotion, fish and amphibian behaviour, to goal-directed a movements in primates and volitional movements in humans. Comparison of these motor systems reveal the existence of some general principles underlying motor control and behavioural choice such that motor systems appear generally to be parallel, distributed processing networks. By discussing the treatment of motor systems in terms of parallel distributed processing systems, this book presents in concentrated form an alternative to the earlier view of motor systems. As such, the book is a must for all neuroscientists interested in the organisation of motor systems and the neuronal substrates of behavioural choice.
For research workers and students in clinical and basic neuroscience.

@qu:...its chief merit is that it demonstrates that a deep understanding of the general principles underlying brain function will depend much more on our theoretical underpinnings and their associated formal mathematical methods and much less on the particular species chosen for study. @source:Neuropsychologia
